RE: Not for weak stomach!
amazing that folks think a 50 would do that. Just because its so big. Same with mags. I saw more damage from my 243 and stupidly using 80 grain bullets on deer than any magnum round I've ever fired.
I will say one thing though. that type of wound could be possible. I've seen a few that are close to that. About 2/3 like others say. Plus you can see that flap of skin on the bottom sorta. If that would be flopped closed the wound would look much smaller.
Depends on how the bullet interacts with the shoulder socket. If you penetrate with a somewhaf fragile high speed bullet from the back and miss the opposite shoulder, only to hit that shoulder socket and blow up, it will blow out a pretty good hole. I've seen that mostly from 270s and 130 Ballistic tip type bullets.
